While stacking the goo balls, make sure to build tower support every so often, or it’ll start to fall over. Depending on the level, you may not be able to build a foundation because you may have to build across a gap. If provided, use the balloons to keep your goo structure from falling over. Balloons can be moved to different areas of your goo network and put back into your structure if you no longer need them.
